Benefits of technology
[0009] It is therefore an objective of the present invention to provide a document positioning apparatus for a document camera, which is able to resolve the problem time wasted in adjusting a position and a focus of an image camera.
[0010] According to the foregoing objectives of the invention, the present invention provides a document positioning apparatus comprising a supporter, a roller device and a document guider. The supporter is disposed under a base of a document camera. A gap is formed between the supporter and a ground surface used to support the supporter and the gap is made large enough for a document to shift. The roller device is installed on a bottom surface of the supporter for moving the document to achieve a desired position. A document guider is formed on an edge of the supporter for guiding the document into the gap under the supporter easily. The roller device is connected to and driven by a motor.
[0011] According to the foregoing objectives of the invention, the present invention provides a document positioning apparatus comprising a supporter. The supporter is disposed under a base of a document camera. A gap is formed between the supporter and a ground surface used to support the supporter. The gap is made large enough for a document to shift. The document positioning apparatus further comprises a document guider. The document guider is formed on an edge of the supporter for guiding the document into the gap under the supporter easily. A base of a light set can be combined with the document positioning apparatus, so that the document can be shifted into the gap of the document positioning apparatus under the base of the light set and the base of the document camera.
[0012] As described above, by using the document positioning apparatus combined with the document camera of the present invention, a document can be moved to a position under the image camera, thereby reducing the need to adjust a focus and a position of the image camera. The presenter can thus devote more attention to the content of the document.
Problems solved by technology
Therefore, by using the document camera, a presenter will save a lot of time by not preparing the presentation data previously.
When the document camera is used to capture a document for presentation, in general, it is necessary for a presenter to move the image camera to a suitable capture position because of the physical limitation of a base of the document camera.
Therefore, it is time-consuming and inconvenient for a presenter to adjust the focus of the image camera.
Therefore, it is inconvenient to capture a document for presentation by using a conventional document camera.

Description
RELATED APPLICATIONS [0001] The present application is based on, and claims priority from, Taiwan Application Serial Number 94117583, filed May 27, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND [0002] 1. Field of Invention [0003] The present invention relates to a document positioning apparatus. More particularly, the present invention relates to a document positioning apparatus for a document camera. [0004] 2. Description of Related Art [0005] Traditionally, a common presentation apparatus is a projector for projecting images. With the advancement of technology, the useful presentation apparatus at present includes a projector with an LCD, a laptop and a document camera. [0006] The document camera may directly present an object on a monitor without previously transforming the object, such as a document or material, into an image file or a document file. The document camera uses a digital camera to capture an image of the object...
